Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hose testing technology, and in particular relates to a braided hose testing device. Background Technology
[0002] Braided hoses are flexible tubes made with platinum vulcanized silicone as the core and polyester mesh braid or steel wire reinforcement layer. The core is treated with multi-layer silicone coating and vulcanization process to form a uniform pressure-resistant structure. They are mainly divided into fiber braided silicone tubes and steel wire braided silicone tubes.
[0003] In existing technologies, braided hoses are continuously pressurized during testing, causing the hose to expand. This expansion can also cause the connection between the testing device and the hose to loosen, leading to leakage and disconnection. To address these issues, we provide a braided hose testing device. Utility Model Content
[0004] The purpose of this invention is to provide a braided hose testing device, which solves the problem of loosening at the connection between the testing device and the pipeline due to expansion in the prior art through the cooperation of the clamp and the abutment plate.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a braided hose testing device, comprising a testing device body. A display screen and multiple control buttons are provided on one side of the testing device body. An inlet pipe and an outlet pipe are respectively connected to both sides of the testing device body. A connecting pipe is connected to the inlet of the inlet pipe. A threaded disc is threaded into the connecting pipe. A conveying pipe is connected to one side of the threaded disc. A pressure gauge is installed on the inlet pipe. Two clamping plates are symmetrically and slidably connected to the side of the threaded disc near the conveying pipe. An installation pipe is penetrating and connected inside the conveying pipe, and two sliding rods are slidably connected to each of the two openings of the installation pipe. A stop plate is fixedly connected to the ends of the two sliding rods that are far apart from each other.
[0006] The present invention is further configured such that tension springs are fixedly connected to the sides of the two clamping plates that are close to each other, and the ends of the two tension springs that are close to each other are respectively fixedly connected to the top and bottom of the conveying pipe.
[0007] The present invention is further configured such that a threaded wire is provided inside the connecting pipe, and the threaded disc and the threaded wire are threadedly connected, and the two sliding rods are fixedly connected to the same spring at their close ends.
[0008] The present invention is further configured such that two guide rails are symmetrically fixedly connected to the side of the threaded disc away from the liquid inlet pipe, and the two clamping plates are slidably connected to the side of the threaded disc close to the two clamping plates respectively.
[0009] The present invention is further configured such that two support plates are symmetrically fixedly sleeved on the outer wall of the liquid inlet pipe, and the pressure gauge is located between the two support plates.
[0010] The present invention is further configured such that valves are installed on the outer walls of both the inlet pipe and the outlet pipe, and the mounting pipe is installed vertically.
[0011] The present invention is further configured such that the two clamping plates are respectively located at the top and bottom of the two abutment plates, an emergency stop switch is provided on the side of the detection device body near the liquid inlet pipe, and multiple control buttons are located below the display screen.
[0012] This utility model has the following beneficial effects: 1. This utility model uses the inner wall of the braided rubber tube to squeeze two abutments closer together. The two abutments close together will squeeze two sliding rods closer together. The two sliding rods close together will compress the spring. The spring will use its elasticity to drive the two sliding rods away from each other. At this time, the sliding rods will drive the two abutments away from each other and abut against the inner wall of the braided rubber tube for fixation. The two clamping plates will also be pulled closer together by the tension of the two tension springs, which can make the two clamping plates close together and clamped to the outer wall of the braided rubber tube for fixation.
[0013] 2. The two clamping plates and the abutment plate of this utility model use the elastic force of springs and tension springs to abut and press against the inner and outer walls of the braided rubber hose, thereby working together to clamp and fix the braided rubber hose. This plays a fixing role for the braided rubber hose, and even in the expanded state, the connection of the braided rubber hose can be fixed to prevent loosening. Attached Figure Description

[0017] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Specific Implementation Example 1 Please see Figure 1-4 This utility model is a braided hose testing device, including a testing device body 1. A display screen 3 and multiple control buttons 4 are provided on one side of the testing device body 1. An inlet pipe 6 and an outlet pipe 5 are respectively connected to both sides of the testing device body 1. The inlet of the inlet pipe 6 is connected to a connecting pipe 10. A threaded disc 14 is threadedly connected inside the connecting pipe 10. A conveying pipe 11 is connected to one side of the threaded disc 14. A pressure gauge 8 is installed on the inlet pipe 6. Two clamping plates 12 are symmetrically and slidably connected to the side of the threaded disc 14 near the conveying pipe 11. An installation pipe 17 is connected through the conveying pipe 11. Two sliding rods 20 are slidably connected through the two openings of the installation pipe 17. A stop plate 16 is fixedly connected to the ends of the two sliding rods 20 that are far apart from each other.
[0019] Specifically: The braided rubber tube is inserted into the outer wall of the delivery tube 11. This allows the inner wall of the braided rubber tube to press the two abutments 16 closer together. The two abutments 16 pressing the two sliding rods 20 closer together will cause the two abutments 16 to move away from each other and press against the inner wall of the braided rubber tube for fixation. The abutments 16 and the clamping plate 12 work together to clamp and fix the braided rubber tube. The liquid entering from the braided rubber tube will flow into the liquid inlet tube 6. Specific Implementation Example 2 Please see Figure 1-4Based on the first specific embodiment, tension springs 18 are fixedly connected to the sides of the two clamping plates 12 that are close to each other. The ends of the two tension springs 18 that are close to each other are fixedly connected to the top and bottom of the delivery pipe 11, respectively. A threaded wire 13 is provided inside the connecting pipe 10, and the threaded disc 14 is threadedly connected to the threaded wire 13. The ends of the two sliding rods 20 that are close to each other are fixedly connected to the same spring 19. Two guide rails 15 are symmetrically fixedly connected to the side of the threaded disc 14 away from the inlet pipe 6, and the sides of the two clamping plates 12 that are close to the threaded disc 14 are slidably connected to the two clamping plates 12, respectively. Two support plates 7 are symmetrically fixedly sleeved on the outer wall of the inlet pipe 6, and the pressure gauge 8 is located between the two support plates 7. Valves 9 are installed on the outer walls of the inlet pipe 6 and the outlet pipe 5. The mounting pipe 17 is installed vertically. The two clamping plates 12 are located at the top and bottom of the two abutment plates 16, respectively. An emergency stop switch 2 is provided on the side of the detection device body 1 that is close to the inlet pipe 6, and multiple control buttons 4 are located below the display screen 3.
[0021] Specifically: the pressure gauge 8 indicates the liquid pressure inside the braided hose. Finally, the liquid reaches the detection device body 1 for testing and is discharged from the outlet pipe 5. Turning the emergency stop switch 2 can stop the detection device body 1. The detection device body 1 can be controlled by multiple control buttons 4. The display screen 3 is used to display the detection data. The flow of liquid in the inlet pipe 6 and outlet pipe 5 can be controlled by using two valves 9.
[0022] The working principle of this utility model is as follows: A braided rubber tube is inserted into the outer wall of the delivery tube 11. This allows the inner wall of the braided rubber tube to press the two abutment plates 16 closer together. The two abutment plates 16 pressing together will press the two sliding rods 20 closer together, which in turn will compress the spring 19. When the force is released, the spring 19 will use its elasticity to move the two sliding rods 20 away from each other. At this time, the sliding rods 20 will move the two abutment plates 16 away from each other and press against the inner wall of the braided rubber tube for fixation. Simultaneously, the two clamping plates 12 will be brought closer together by the tension of the two tension springs 18. This allows the two clamping plates 12 to clamp together and fix against the outer wall of the braided rubber tube, thus enabling the abutment plates 16 and clamping plates 12 to work together to support the braided rubber tube. The hose is clamped and fixed. The liquid entering from the braided hose flows into the inlet pipe 6. The pressure of the liquid inside the braided hose can be known through the pressure gauge 8. Finally, the liquid reaches the detection device body 1 for detection and is discharged from the outlet pipe 5. Turning the emergency stop switch 2 can stop the detection device body 1. The detection device body 1 can be controlled through multiple control buttons 4. The display screen 3 is used to display the detection data. The flow of liquid in the inlet pipe 6 and the outlet pipe 5 can be controlled by using two valves 9. Rotating the installation pipe 17 will drive the delivery pipe 11 to rotate. The rotation of the delivery pipe 11 will drive the threaded disc 14 to rotate and disengage from the threaded wire 13 for disassembly. The guide rail 15 plays a limiting and guiding role when the two clamps 12 are raised and lowered.
